Matrix composing and line casting machine



y 2, 1933- c. A. ALBRECHT MATRIX COMPOSING AND LINE CASTING MACHINE Filed Sept. 11, 1931 i or Patented May 2, 1933 UNITED STATES r ce CHRISTIAN AUGUSTUS ALBRECHT, OF BERLIN, GERMANY, ASSIGNOR TO MERGE-N- THALEE LINOT'YPE COMPANY, OF BROOKLYN, NEW YORK, A COMPANY OF NEW YORK MATRIX COMPOSING AND LINE CASTING MACHINE Application filed September 11, 1931, Serial No. 562,207, and in Germany September 13, 1930.

In matrix composing and line casting machines, it has already been proposed, by the use of suitable moulds and matrices, to cast line-spacing material such as blank slugs, low leads and the like. As such line-spacing material need not be produced with perfectly straight edges or side faces, it is not necessary to subject the cast slugs to the action of the trimming knives. On the other hand, these blank slugs must be efficiently guided during their passage from the mould .to the slug galley. It is therefore desirable in such cases to use the knife block as a guide by replacing one of the knives by a spring-pressed guide plate or the like, which ensures the slugs travelling in the direction of their ejection. In arrangements of this character, as heretofore proposed, the springs occasionally fail to act and as a consequence thereof, the slugs assume an inclined position, and as the slugs are ejected by a thin blade, there is a danger of the blank slugs about to be ejected, becoming jammed in the mould and causing damage to the machine.

The present invention overcomes these difliculties by providing a guide whose width corresponds with the thickness. of the blank slug then being cast, the said guide being preferably controlled by the mould itself. For this purpose the mould is provided with a roller or a cam or the like which is adapted to bear against an abutment or projection connected with one of the guiding walls or surfaces, and'thereby adjust that wall relatively to the complementary wall, so that the distance between said walls will correspond with the width of the mould then in use.

In the accompanying drawing, one con-- structional form of the invention is illustrated and 1n thls draw1ng:

Figure 1 1s a front elevatlon of the guiding mechanism Figure 2 a section on the line 22 of Figure 1, and

Figure 3 is a section on the line 33 of Figure 1. I

The moulds b, as ordinarily are carried on 3 the mould disc a. The trimming device which comprises a stationary and an adto the plate as by screws g and is movable in a guide it on the vise frame 0.

Springs i attached at one end to the blade f and at the other end to the guide h tend to move the blade, and with it the plate 0 towards the stationary knife d. This movement is limited by a plunger or bolt n, to which is attached a stud 0 and which is moved rearwardly in a socket k by a spring 39, encircling the said stud, which latter is provided with a head to limit the movement The knife (Z there- 7 in that direction. A roller g, pivotally' mounted on the bolt a, is adapted to travel over an edge cam or the like 1", attached to the mould I). 1

The mode of operation of the device is as follows When the mould is not in ejecting position, the springs'i'hold the plate 6 as near to the stationary knife 0? as is permitted by the slot on, against the left-hand of which (as viewed in Figures 1 and 2) the socket is is then in contact. When the mould 6 arrives at the ejecting position, the cam 7' en gages with the roller Q and thereby the blade f with the plate 6 is moved outwardly against the action of the springs i, so that said plate will be adjusted at the correct distance from the fixed knife d, to enable it to act as a guide for the blank slug next to be ejected.

The resilient mounting of the roller 9 on the blade f, is provided for the purpose of maintaining said roller in engagement with the cam 1" throughout the usual forward and backward movement of the mould and mould carrier.

The before described arrangement can be modified without departing from the spirit of the invention, for example, the roller can be mounted on the mould and adapted to engage a cam operatively fast to the plate 0. The stationary side of the slug guide need not necessarily be constituted by the stationary knife, for, in its place another guide wall or the like could be used. Likewise the cam 9* need not be mounted directly upon the mould b, but could for example also be arranged on the mould carrier a.

Having described my invention, I declare that what I claim and desireto secure by Letters Patent is 1. In a matrix composing and line casting machine, the combination with a casting mould adapted to cast blank slugs and the like, and of which one wall is movable for adjustment to effect the casting of slugs of different thickness, of a nontrimming slug guide through which pass the slugs ejected from the mould, comprising two walls of which one is adjustable bodily relatively to the other to vary the distance between them to correspond with the distance between the mould walls.

2. In a matrix composing and line casting machine, the combination with a casting mould adapted to cast blank slugs and the like, and of which one wall is movable for adjustment to effect the casting of slugs of different thickness, of a slug guide through which pass the slugs ejected from the mould, comprising two walls of which one is adjustable relatively to the other to vary the distance between them to correspond with the distance between the mould walls, springs tending to move the adjustable guide wall in one direction, and co-operating cam and roller on the mould and adjustable guide wall, adapted to move the latter antagonistioally to the springs.

3. In a matrix composing and line casting machine, the combination with a casting mould adapted to cast blank slugs and the like, and of which one wall is movable for adjustment to effect the casting of slugs of different thickness, of a vise frame, a slug guide on said vise frame, through which pass the slugs ejected from the mould, comprising two walls of which one is adjustable relatively both to the vise frame and to the other wall to vary the distance between said walls to correspond with the distance between the mould walls, springs anchored to the vise frame tending to move the adjustable guide wall in one direction, a guide on the vise frame for the adjustable guide wall, and co-operating cam and roller on the mould and adjustable guide wall adapted to move the latter antagonistically to the sprmgs.
